Madrid Project on the Management of Chronic Obstructive Pulmonary Disease With Home Telemonitoring

The purpose of the study is to verify the clinical effectiveness of a managed home telemonitoring program in patients with severe COPD against usual clinical practice, as measured by the decrease in the number of exacerbations, number of hospitalizations, hospital days and emergency room visits in a 12 month period The primary endpoint of effectiveness is "severe exacerbations avoided." The main hypothesis is that patients with severe or very severe COPD patients managed with a home telehealth program have better outcomes than patients managed according to usual clinical practice.
